  2. Metabo TWIN 18V sds drill - 7AH BATTS - KHA 36-18 LTX 32 - oztooltalk review

    in Power Tools

    Posted

    I guess bpm does play a part, the shaft of every drill bit or chisel tip is only going to be able to absorb so many impacts before failure. The impact energy will definitely be the overriding cause of failure, particularly with the wider flat chisel tips, their larger surface area will offer up more resistance to each blow, this will all have to be absorbed by the shaft. 

     

    Any metallurgists out there care to comment?

    I buy drills because I like them, I like the tech that's built in to them, I like what they can do for me. An sds with chipper function will chase a masonry wall out in minutes, but when I was an apprentice we didn't have such luxury, it was all by hand. So I'm not prepared to give up that luxury be it through theft or breakdown, so I keep several different sds drills on hand. 

     

    Same goes for combi drills, good to have spares. Besides, they all bring their own thing to the table, no two are ever alike. 

     

    Then there's the Ryobi kit that I keep, they're basically loaners. If they get lost or stolen I'm not too bothered. The high end kit is for me and me alone. If I drop and damage one of them, it's on me.

  9. Will brushed cordless tools become obsolete?

    Some tools don't need to be brushless. Brushless has been over-hyped. Hilti is a great example, they use a 4 pole motor, rather than a 2 pole, on their badass drill that is pushing 1060 in-lbs of torque. The efficiency and run time is almost exactly the same as a brushless too. The big difference is that drill work forever, dust, moisture, cold etc. It doesn't have the limitations of so much control electronics and potential failure points.
    Heat kills electronics, tools under load produce heat.

    I want Hilti in my arsenal, but until I win the lottery that ain't gonna happen. :'(

    Of course, hence why I usually write "20v Max" as opposed to simply 20v.  I distinguish between the two by their branding, as in the US they are simply 18v XRP and 20v Max.  Marketing aside, it is a great way to point out that they are indeed different systems, eliminating the confusion between which style of battery a tool uses.  Not a big deal for most of us here, but it avoids returns and bad publicity, even while drawing the ire of other consumers.

     

    It's funny how much hatred DeWalt gets for this strategy while Milwaukee's M12 line just slides under the radar.  Maybe I should criticize my Fuel tools...I still haven't found the gas tank. :D

     

     

    Similar to how most 12v car batteries are nominally 13+ volts and alternators put out over 14v.  

     

    Gas tank! That's class! 

     

    Yeah, I love my Milwaukee kit, but I'll happily criticise the labeling.

    Good question.  From a consumer viewpoint, brushed tools will always be "better"--less expensive, user serviceable, less prone to damage from abuse/accidents.  Just about everyone here is a diehard tool user/collector, so naturally more runtime and better specs (as most brushless tools boast of) appeal to us.  Harry Homeowner, though, is likely much less discerning, caring more about price and perceived quality.  In my opinion, this is why DeWalt continues to sell new 18v tools.  They are tried and true tools that many people think are still top of the line.  A few months back, I paid a local guy to help me hang drywall.  He brought his 18v XRP drill, but I'm fairly certain my 20v Max stuff changed his opinion.  His batteries died quick, so he found himself using my brushless drills and impact driver more often than not, and he was amazed by the screwgun with collated magazine.  I eventually let him use an adapter to keep running his drill with the 20 batteries.

     

    Anyway, I digress.  So long as they continue to see profits, major tool manufacturers will offer brushed tools.  They may slowly reduce the types of bare tools and single tool kits, but larger combos will probably continue to be offered at prices far below those of premium brushless combos.  Think of the DCS393 and DCS381; both are saws with cost-cutting features that are solely offered in combos.  Similarly, look at recent special buy combos.  DeWalt and Milwaukee offer three tiers of drill/impact kits nowadays: brushed, budget brushless, and pro brushless.  The brushed (e.g. DCD780/DCF885) is noticeably cheaper than the budget brushless, which is in turn significantly cheaper than the pro brushless.  

     

    Simply put, proven designs (DeWalt 18v, brushed tools in general) will continue to be sold until they are no longer profitable.  Most consumers don't need to pay more for a brushless tool, so they will continue to buy basic models over more premium offerings.  Meanwhile, many of us will continue to buy the latest BL/Fuel/whatever else our preferred brands offer and scoff at those buying that 18v XRP kit at Lowe's (I'm exaggerating; I don't think less of anyone due to what they are buying and am actually glad when I see anyone spending their hard-earned cash on a tool).

     

    TLDR; Brushed tools will be around for the foreseeable future.

     

    You do know that 18 and 20 are one and the same? There's no difference in voltage, it's just different marketing laws in different parts of the globe. In the UK, it's strictly 18 Volts, not 20 as that's only achieved at fully charged and drops within minutes of squeezing the trigger. 

     

    If you're referring to old nimh technology, then yes, world's apart!

    I bloody hope not! Just bought my first brushed machines in years and they're reminding me just how good they are for low speed throttle control! The ones I've bought are Bosch, but I'm sure Hilti still produce a lot of brushed machines. 

     

    Also, as you mentioned, brushed is far simpler in how they work, this makes them cheaper and less prone to failure.

  16. Flexvolt Battery Won't Charge

    Lithium cells have very strict tolerances that must be adhered to. Don't go over voltage, don't go under. If you've managed to deep-discharge it, it is possible to "jump start" it, but it'll never be the same again. They have plenty of protection built-in to protect the cells, but you can't protect a duff cell. Duff cells happen, that's part of mass-production, especially with lithium cells. 

     

    If it's borked, just let Dewalt swap it.

    I call it a slidehammer, have also heard them called a peashooter. Put up to 3" nail in the tip and the handle slides and hits the nail in. Sometimes you just can't get a gun or hammer in a  gap

     

     

    I don't think I've ever heard of those, I'll have to search for vids of one in action.

    Yesterday I used my old corded sds drill. I'd forgotten just how good a brushed drill is for throttle control, so smooth at low speeds. 

     

    Yes, BL drills are powerful and efficient, but they'll never have the low speed control that brushed has. It's possible to make a BL drill with better low speed control, but it gets very pricey.
